What should I do if the system does not display anything within 30 seconds of powering on?

If nothing appears on screen within 30 seconds of turning on the power, the system may have failed a power-on self test (POST). You should check the jumper settings and connections, or call your retailer for assistance. You can also refer to the BIOS beep code table — for example, one continuous beep followed by four short beeps indicates a hardware component failure.
